Alectro USB (Universal Serial Bus) Wall Plates are available in a variety of configurations, but we can also custom make one for your particular purpose. The most commonly used USB connector is a USB-A Type female to female which is the default connection in all our USB Wall Plates. Alectro USB Wall Plates are perfect for both PCs and Macs and can be used to connect keyboards, USB printers, scanners, external hard drives and other standard USB devices.
